Mark Zuckerberg famously claimed that “a phone just doesn’t make any sense“. However, Pocket-lint says their reliable source has confirmed that the HTC Opera UL is an OEM product. “It is the Facebook phone, made for Facebook.”

The Nokia 920T may support 2.6 GHz TD-LTE next year. China Mobile has began testing 20,000 4G base stations in China, and it expects to see 200,000 up and running by the end of 2013.

Google (with Google+), Microsoft (with Skype) and Apple (with Facetime) as well as Facebook and Amazon might increase app sales and advertising revenues with a low cost ($10-$20/mo) data package, as a Mobile virtual network operator. Spectrum from T-Mobile and Sprint is available.

But the 2.6 GHz band will be limited to spotty urban core service. Voice fallback and roaming would require big telco support. A Facebook phone (or Amazon phone) would have limited benefit if they’re unable to get a good wholesale price on spectrum and deliver real value. It would be a niche product at phone stores. Maybe a Firefox OS mobile phone will make HTML5 “apps” universal.

If Google, Microsoft and Apple bought TV-band 600 MHz spectrum in 2014, and delivered Voice over LTE at 2.6 GHz, it could create a competitive environment — with roaming — in a Multi-verse of standards. M-theory.
